The right answer is "B. She joined local politics and saw women playing a secondary role to men."
Here is a quick explanation:
Shirley Chisholm (1924-2005), an Afro-descendant, living in the Brooklyn borough of New York, was born into a society stoned by prejudice and segregation. At that time, although most blacks were doomed to secondary jobs, Shirley managed to overcome obstacles and elect the first woman to occupy the House of Representatives, where she later founded the congressional women's bench. Although Chisholm's achievements represented a huge change in American politics, her greatest "victory" came years later, when she became the first black woman to run for the highest office in the country.
According to the Smithsonian, when she joined Congress in 1968, she made it clear that she would not have a submissive position since she did not agree with the role of submission imposed on women of the time. Shirley intended to change the dominant status quo at the time.
